GAGE-COCK.

SPECIFICATION forming part of Letters Patent No. 444,360, dated January6, 1891.

Application filed August 12, 1890. Serial No. 361,841. (No model.)

To all whom t may concern:

Be it known that I, JOSEPH J UNGBLUTH, a citizen of the United States,and a resident of Erie, in the county of Erie and State of Pennsylvania,have invented certain new and useful Improvements in Gage lor Test Cocksfor Steam-Boilers; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification.

My invention relates to improvem'ents in gage or test cocks forsteam-boilers of that class in which the steam orifice or passage isclosed by means of a' valve carried bya weighted lever, which is held inproper vposition by gravity.

The object of the invention is to provide a device of the abovedescription which shall be simple and economical in construction,durable in use, and effective and reliable in operation, and in whichthe valve carried by the weighted lever closing the steam-passage can beshifted or adjusted so as to present a new surface thereto in order tocompensate for wear.

The invention consists in the novel combination and construction ofparts hereinafter fully described, and specifically pointed out in theclaims.

In the accompanying drawings, Figure 1 represents a side elevation of agage-cock constructed in accordance with my invention. Fig. 2 is acentral sectional view, and Fig. 3 is a plan view, of the same.

In the said drawings, the reference-numeral 1 designates a nozzle orcoupling provided with screw-threads at one end, by which it may beinserted and secured in a steamboiler and having a central bore 2. Theother end of this nozzle is formed with a iiat extension 3, having itsends double-beveled, as at 4. It is also formed with auupwardly-projecting lug 5 and has a steam-passage 6 communicating withthe bore of the nozzle and terminating at the upper beveled part 4.

The numeral 7 designates a weighted lever provided with the studs 8 8,which embrace and are pivoted to lug 5. Intermediate of the studs 8 Sand the ball or weighted end 9 of the lever is a circular portion 10,provided with an annular recess to receive the valve 12, which consistsof a disk of rubber, leather, metal, asbestus, or other material whichmay be found suitable. The lower part of this circular portion isprovided with a groove or is cut away at 13, which receives the free endof the nozzle 1.

The numeral 14 designates an annular recess, within which seats thewasher 15,having peripheral projections 1G, said Washer forming a coverto the recessed portion 10, and is provided with a central aperture,through which passes a stem or rod 17, and which also passes through thevalve and the wall of the said circular portion. One end of this rod orstem is formed with a thumb-piece 18, while its other end isscrew-threaded and provided with a binding-nut 19, while theintermediate portion is square or angular to prevent the disk fromturning thereon.

The operation will readily be understood. When in normal position, thevalve-disk will seat against the beveled end of the nozzle or coupling,closing the steam-passage, being held in this position by gravity. Toopen the valve, it is only necessary to raise the ball or weighted endof the pivoted lever. In order to present a new valve-seat to thesteam-passage to compensate for wear, the binding-nut 19 is loosened andthe disk slightly turned by means of the thumb-piece 18, and in case thedisk should become completely worn out it can be replaced by another bysimply taking off nut 19, withdrawing the stein 17 and washer 15, andremoving the disk and placing a new one on the stem. The parts are thenput together and the binding-nut applied and screwed home.

From the above it will be seen that the valve-disk can 'present a largenumber of different seats or faces to the steam-passages, as inadjusting it to form a new seat it is only necessary to give it but avery slight turn. The disk can also be removed and replaced by anotherunder full boiler-pressure, and the invention possesses other advantagesnot necessary here to enumerate, as they will be obvious to thoseskilled in the art.

Having thus described my invention,what I claim is 1. In a gage-cock,the combination, with a IOO coupling having a steam-passage, of apivoted 1.5, having peripheral projections 16,1l1e stein lever having acircular recessed portion, a or rod 17, having thumb-piece 18, square orWasher, adsk-valve, and a stem having a angular portion 20, and thebinding-nut 1f),
